HP XP7 Command View Advanced Edition Administrator Guide (Web Version) (TK981-96004, May 2014)

The SMI-S specifications, which Device Manager conforms to, define the interfaces for devices
that make up a storage network, such as storage systems, virtual storage systems, switches, and
hosts. The functions that need to be provided by the management service to manage the devices
are grouped in a profile for each device.
The profiles used by the CIM/WBEM functions of Device Manager are the Array profile and its
subprofiles. The Array profile defines the interfaces for storage systems.
Indication function
The indication function is the event notification function defined by CIM. When an event occurs
in a CIM server, the CIM server reports the indication instance, which shows the information
about the event (such as generation or deletion of a CIM instance), to CIM clients. For a CIM
client to receive indications, its location and transmission conditions for indications must be re-
gistered in the CIM server beforehand. For details on how to register them, see the SNIA website.
Device Manager reports the occurrence of the following events:
• Generation of a volume
• Deletion of a volume
• Allocation of a LUN path
• Cancellation of a LUN path
Service discovery function
Device Manager provides the service discovery function based on the Service Location Protocol
(SLP).
The SLP is undergoing standardization by IETF and provides a way to discover desired services
available in a network. For details on the SLP, see RFC2608.
Just by specifying the type of service, SLP clients can acquire information (such as URLs) about
how to access the available services, and information about service attributes.
In Device Manager, the Device Manager server uses the SLP to report information about the
WBEM Service.
Performance information acquisition function
Device Manager acquires the following types of information as storage system performance in-
formation:
• Port-related information
Total I/O count
Data traffic
• Volume-related information
Total I/O count
Data traffic
Number of read I/Os
Number of read I/Os that hit the cache
Number of write I/Os
Number of write I/Os that hit the cache
Specifying a namespace
Device Manager supports versions 1.1.0 through 1.5.0 of SMI-S. The namespace that is used to
connect to Device Manager (CIM server) must be specified on CIM clients.
You can specify a namespace by using the follow format:
• Specify the SMI-S version.
